Abstract
BACKGROUND: Different bariatric surgeries have demonstrated different effectiveness for weight loss and glucose control in obese persons with diabetes, over a short follow-up time. The aim of this study was to compare weight loss, glucose control, and diabetes remission in individuals with type 2 diabetes, after three types of bariatric surgery: gastric banding (GB), sleeve gastrectomy (SG), and Roux-en-Y gastric bypass (RYGB), with 5 years follow-up. METHODS: A retrospective study was conducted on bariatric surgeries performed during 2002-2011 in a large nationwide healthcare organization. RESULTS: Of 2190 patients, 64.8 % were women. The operations performed were 1027 GB, 1023 SG, and 140 RYGB. Mean BMI ± SD at baseline, 1 year postoperatively, and 5 years postoperatively were 43.5 ± 6.18, 37.1 ± 6.35, and 35.5 ± 6.48 for GB; 43.6 ± 6.42, 34.4 ± 6.08, and 35.3 ± 6.7 for SG; and 42.8 ± 5.81, 32.8 ± 4.9, and 34.1 ± 5.09 for RYGB. Mean HbA1c ± SD at baseline, 1 year postoperatively, and 5 years postoperatively were 7.6 + 1.58, 6.5 + 1.22, and 6.8 + 1.48 for GB; 7.7 + 1.63, 6.4 + 1.18, and 6.7 + 1.57 for SG; and 8.0 + 1.78, 6.3 + 0.98, and 7.04 + 1.42 for RYGB. At 1 year follow-up, 53.2 % had achieved remission; at 5 years, 54.4 %. Remission rates at 5 years were similar for the three surgeries. Five-year remission was inversely associated with baseline HbA1c and with treatment with insulin at baseline and positively associated with BMI. CONCLUSIONS: For all three surgeries, diabetes remission was higher than the baseline after 5 years; mean BMI and HbA1c decreased considerably during the first year postoperatively and remained lower than basal values throughout follow-up. Early improvements were greatest for RYGB, though the advantage over the other operations diminished with time.
